    event handler calls api function after the execution of flag condition, so I am getting the flag undefined. @Alan

    You've got async code in there. The event handler returns before the checkCookiePresent() Promise is fulfilled.

    Is there a synchronous version of the checkCookiePresent code you can use? I'm not sure why checking for a cookie would need to use promises?

    what would be best way then to hit backend API and after the response will decide to return boolean for event handler.

    You'd need to make the Ajax call and then decide if you want to trigger Editor to display or not - e.g.

    $.ajax({
      url: '...',
      success: json => {
        if (json.show) {
          editor.create(); // or whatever editing action is required
        }
      }
    });
    

    The preOpen event is synchronous.
